# --description--

A tuple is another built-in data structure in Python. Tuples are very much like lists, but they are defined with parentheses `()`, instead of square brackets. Also, tuples are immutable, unlike lists.

```py
my_tuple = ('larch', 1, True)
```

Your `constraints` list is going to store tuples. The first item of each tuple will be a constraint parameter.

Modify the `constraints` list assignment by adding a tuple to your list. Use `nums` as the first item and an empty string as the second item.

# --hints--

You should add a tuple to the `constraints` list.

```js
({ test: () => assert.match(code, /constraints\s*=\s*\[\s*\(.*\)\s*\]/) })
```

You should add `(nums, '')` to the `constraints` list.

```js
({ test: () => assert.match(code, /constraints\s*=\s*\[\s*\(\s*nums\s*,\s*("|')\1\s*\)\s*\]/) })
```

## --seed-contents--

```py
import secrets
import string


def generate_password(length, nums, special_chars, uppercase, lowercase):
    # Define the possible characters for the password
    letters = string.ascii_letters
    digits = string.digits
    symbols = string.punctuation

    # Combine all characters
    all_characters = letters + digits + symbols

    while True:
        password = ''
        # Generate password
        for _ in range(length):
            password += secrets.choice(all_characters)
--fcc-editable-region--        
        constraints = []

--fcc-editable-region--
    return password

# new_password = generate_password(8)
# print(new_password)
```
